Thermal annealing effect on the structural and magnetic properties of barium hexaferrite powders
Samples examined in this experimental work were in the form of hexagonal barium ferrite with various temperatures annealing. Barium hexaferrite (BaFe12O19), is of great importance as permanent magnets, particularly for magnetic recording as well as in microwave devices. The variation of the temperatures annealing was found to affect coercivity, mean effective anisotropy field, magnetic viscosit...
متن کاملStructural and Magnetic Properties of Nanosized Barium Hexaferrite Powders Obtained by Microemulsion Technique
Thin hexagonal barium hexaferrite particles synthesized using the microemulsion technique were studied. A water-in-oil reverse microemulsion system with cetyltrimethylammonium bromide (CTAB) as a cationic surfactant, n-butanol as a co-surfactant, n-hexanol as a continuous oil phase, and an aqueous phase were used. The microstructural and magnetic properties were investigated. The particles obta...
متن کاملOrder-disorder and magnetic exchange interactions in substituted strontium hexaferrite SrAxFe12-xO19(A=Ga, In)
The unusual magnetic behavior of the 1% site in SrGa,Fe12-,Olg (8.3Cu<6.0) and SrInXFc,,_,XO,, (0.3~~~1.4) has been investigated by means of 57Fe Miissbauer spectroscopy at 298 IL The bifurcation of the 12.k MGssbauer subspectrum into 12k, and 12k2 components vf widely differing intensities has been confirmed for both Ga”+ and 18. The bifurcation is apparent at s values as low as 0.3, and the l...

15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
